Despite being able to secure professional hot messes such as Tila Tequila and Jason Wahler, the fourth season of VH1’s Celebrity Rehab is still being postponed.

According to TMZ, filming for the new season was supposed to begin this week, but producers of the show were unable to fill up the roster. Despite Tila, 28, and Jason being signed on, the show still had a hard time finding more celebs, and another big issue was the show could not secure a big star.

Sources reveal that producers offered Lindsay Lohan $1 million and her own show, but Lindsay turned them down.

As for former reality stars Tila and Jason, TMZ reports Tila’s problem is with prescription pills with sources saying she even snorts Ambien. And as for Jason, who has appeared on Laguna Beach and The Hills, he has been arrested multiple times in recent years for alcohol related incidents.

TMZ also confirmed “Bone Thugs-N-Harmony” rapper Bizzy Bone was also on board to appear on the show.
